I know this question has been asked before, and I apologize for not being able to find my answer in search. Will a copy of my passport be good enough to get back on the ship at our cruiseports? We will be stopping in Cozumel, Limon, & Colon. We leave this Saturday!

A driver's license will suffice. The ship will tell you "a photo ID and your cruise card" will be needed to leave and return to the ship. A copy of your passport might confuse the guards. I know we've talked about passport copies in the past on this forum. My thinking is that a passport copy is useful if something happens ashore and you need to provide information to the police, local immigration authorities, or the U.S. Embassy/Consulate.

In the ports you listed I have always brought my license as my official ID.

Dave,
I am told by the cruise line I don't need a passport if it is a closed loop, is this an example of a closed loop cruise? This would be good to know, I was thinking it was a closed loop if it stopped at one Island and was back in the USA, EX: NY to Bermuda and back.

A closed loop cruise is defined as one which starts and ends at the same U.S. port and visits ports under the exclusion for the Western Hemisphere Travel Initiative (WHTI). This includes Canada, Bermuda, Alaska, Bahamas, and other ports in the Caribbean, Mexico, and Central America. Thus, leaving from NYC for Bermuda, and returning to NYC, is exempt from the passport requirement as long as you depart and return on the ship. A passport is required if you had to fly home from Bermuda for some reason.

We go to the San Diego Wild Animal Park and have season passes. They require you show the season pass and a photo ID. They told us to just copy our DL and laminate it o the pass. We did that and have had no trouble until a few days back.
We were at an accident site and the CHP needed our ID. When I was getting my DL out he noticed the other one. I explained to him why we had copied it, but it did not amuse him. He told us it is unlawful to copy any State or Federal ID, including passports.
Do not know if he is correct or not but we did anyway with our copied versions.
